Banksy, a pseudonym for the elusive artist who first emerged in the streets ofBristol, England and whose real identity is unknown, unleashed a slaughterhouse delivery truck filled with squealing, animatronic lambs, cows and chickens on the city's streets, which was shown on the video posted on his website.

The truck has toured the Meatpacking District and will then go around the rest ofNew York for the next two weeks, according to Banksy's website.

Banksy has become a coveted contemporary painter in the art world, known for his trademark spray-paint stencils on buildings that offer social commentary. The artist appeared in and directed the 2010 Oscar-nominated documentary "Exit Through the Gift Shop" with his face and voice obscured.

Earlier this year, two spray-painted murals by Banksy were pulled from an auction in Miami, including one entitled "Slave Labour," after questions arose about the ownership of the works and how the auction house obtained them.

"Slave Labour" eventually sold at a private auction in London for $1.1 million in June.
